Objective: The purpose of this study was to find out how the back instability during clam exercise (CE) causes changes in pelvic rotation and hip joint abductor muscle activity, and to find out the effects with different methods of application of pressure biofeedback. Design: Comparative study using repeated measures. Methods: Each subjects performed the clam exercise (CE) without pressure biofeedback, the clam exercise with pressure biofeedback applied to the back (CE-PBU to back), and the clam exercise with pressure biofeedback applied to the side (CE-PBU to side). The amount of pelvic rotation was measured using myomotion. And the muscle activity of the muscle gluteus medius and the tensor fasciae latae was measured using EMG device. One-way repeated measures ANOVA followed by the Bonferroni post test were used to compare the EMG activity in each muscle and pelvic rotation angle during the CE, CE-PBU to back, CE-PBU to side. Results: The amounts of pelvic rotation was the lowest in CE-PBU to back (p< 0.05) and the ratio of muscle activity of the muscle gluteus / tensor fasciae latae was the highest in CE-PBU to back (p< 0.05). Conclusions: It is thought that, in order to stabilize the waist-pelvis and increase hip joint muscle strength in subjects with back instability, applying clam exercise with pressure biofeedback applied to the lower back is effective in improving waist-pelvic movements and selectively strengthening the muscle gluteus medius.

This study was conducted to test the effect of brisk walking & muscle strengthening exercise program on bone mineral density(BMD) of the lumbar & femur in rheumatoid arthritis women. Research design was a quasi-experimental study of non-equivalent control group pretest-posttest design(16 weeks). 14 for the experimental group and 14 for the control group were selected from the outpatients on rheumatoid arthritis clinic of Dong-A University Hospital. The experimental group underwent 16 weeks of brisk walking and muscle strengthening exercise. Bone mineral density was measured before and after 16 weeks of exercise by DXA at lumbar spine, femoral neck, Ward's triangle and trochanter. The results were summarized as follows : 1. BMD of the lumbar spine in experimental group who carried out the brisk walking and muscle strengthening exercise was not significantly increased after 16weeks and there was no significant difference between experimental and control group(U=70.00 p>.05). 2. BMD of the femoral neck in the experimental group who carried out the brisk walking and muscle strengthening exercises was significantly increased after 16 weeks(Z=-2.901 p<.01). But, there was no significant difference between experimental and control group(U=83.00 p>.05). 3. BMD of the femoral Ward's triangle in the experimental group who carried out the brisk walking and muscle strengthening exercises was significantly increased after 16 weeks (Z=-2.355 p<.05). But, there was no significant difference between experimental and control group(U=86.00 p>.05). 4. BMD of the femoral trochanter in experimental group who carried out the brisk walking and muscle strengthening exercise was not significantly increased after 16weeks and there was no significant difference between experimental and control group(U=75.00 p>.05). These results suggest that brisk walking and muscle strengthening exercise program has an effect on promoting bone mineral density of femoral neck and Ward's triangle in rheumatoid arthritis women.

Background: Lumbar stabilization exercise and gluteal muscle strengthening exercises are widely used to treat for lower back pain patient. The present study aimed to compare the effects of lumbar stabilization exercise and gluteal muscle strengthening exercises on chronic lower back pain with lumbar spine instability, with regard to pain intensity, disability, and psychosocial factors. Methods: Among 53 patients with chronic lower back pain, those with spine instability were selected using 5 examination tests. The selected 28 patients were randomly assigned to lumbar stabilization exercise group (LSE, n=15) and gluteal strengthening exercise group (GSE, n=13). Each group performed the corresponding exercise for 40 minutes, twice a week for 4 weeks. To analyze and compare the effects, pain intensity, the level of low back disability, and psychosocial factors were assessed before and after intervention. Results: There was significant difference in lower back pain intensity between the two groups before and after intervention. The change in low back disability was significant in the GSE group alone following intervention (p<.05), but no other significant difference was found between the groups. Among psychosocial factors, the changes in the fear-avoidance beliefs questionnaire (FABQ)-physical activity and FABQ-total were significant in the LSE group alone following intervention (p<.05). However, no significant difference were found in these factors between the two groups before and after intervention. Conclusions: LSE and GSE for lower back pain with lumbar spine instability showed no significant difference for pain intensity, physical disability, or psychosocial functioning.

Purpose: This study aimed to verify the impact of the time that the sitting posture is maintained on changes in muscle performance and head alignment. Methods: The subjects of this study were healthy adults aged between 20 and 30 years. Ninety-three subjects participated in this study (male: 57, female: 36). The subjects were divided into a one-hour group, a two-hour group, and a three-hour group. All the subjects adjusted the height of their chair to a comfortable position and then seat for one, two, or over three hours. Both prior to and after the experiment, the muscle performance (muscle strength, endurance, and flexibility) of the subjects was measured. Results: In the 2-hours and 3-hour group, muscle strength, flexibility and endurance reduced significantly before and after the study, and the head alignment significantly changed. Conclusion: Thease findings showed that sitting continuously for longer than two hours decreases muscle strength, endurance, and flexibility. A flexed posture affects the muscle performance of the lumbar region and may result in problematic postures, such as a forward head position.

PURPOSE: This study researched the effects of different types of high heels on the muscles surrounding the cervical spine, the thoracic spine, and the lumbar spine by analyzing muscle activation of the paraspinal muscles during walking while wearing high heels. The high heels were all of the same height: 8cm. METHODS: The 28 subjects in this experiment were females in their 20s with a foot size of 225-230mm. To measure the muscle activation of the paraspinal muscles, EMG electrodes were attached on the paraspinal muscles around C6, T7, and L5. The muscle activation during walking while wearing 8cm high wedge heels, setback heels, and french heels was measured. The measurements were performed 3 times each and the mean value of the result was used for analysis. Two kinds of velocity were used in this study. One of the velocity was 2.5 m/s. The other was 3.5 m/s. RESULTS: The muscle activation of paraspinal muscles increased significantly according to increase of walking velocity. But there was no significant difference according to the heel types. CONCLUSION: In view of the results, the height of heels and the velocity of walking are more convincing variables than the width of the heels on the muscle activation of paraspinal muscles. So wearing high heels is not recommended for those who have pain or functional problem of cervical and lumbar vertebrae.

The purpose of this study was to find the effects of the lumbar stabilizing exercise on the isometric lumbar extension strength and the range of motion of lumbar extension. 16 healthy subjects were recruited (9 males, 7 females, mean age 25${\pm}$3.2). They performed 5 types of exercises 5 times per week for 4 weeks. We evaluated isometric trunk extension strength (0, 12, 24, 36, 48, 60, $72^{\circ}$) by MedX(Ocala, FL) and measured range of motion of lumbar extension. All measurements were measured at pre-exercise and 4 weeks post-exercise. The results of this study were summarized as follows; After 4 weeks of exercise, isometric lumbar extension strength was generally increased but there were only significant differences at $12^{\circ},\;24^{\circ},\;48^{\circ}$. The range of motion of lumbar extension was increased (p<.05). The isometric lumbar extension strength correlated with the range of motion of lumbar extension. In conclusion, our results have shown that lumbar stabilizing exercise influenced both lumbar extension strength and range of motion of lumbar extension.
